We currently have a standalone customers service in moltin (https://moltin.api-docs.io/v2/customers), and are in the process of linking it to orders/carts as well as bringing it into the documentation. Expect to see an announcement in the forum over the coming weeks!

You’ll be able to swap an email address and password for a unique token. This token can be used as the {identifier} in calls to some of the customers endpoints that in turn gives you access to resources for that customer. Again, we’re working on the documentation on this as it’s not complete, so stay tuned!
